Usually when a bird is using wings for balance it indicates a leg injury,although i am not ruling out internal injuries. Do you have a cage to place her in and bring her inside home. Check her legs over very carefully can you feel any swelling,see if you can figure out which leg it is. Give her electrolytes for shock,keep her warm(when ill/injured birds cannot regulate their body temp).
Panting can indicate pain/stress/overheated,i'm guessing in her case pain/stress are the problem.
Repost with information i have requested and we can go from there with treatment options.
